At the Chicago Comic and Entertainment Expo on April 14, Marvel Entertainment is auctioning a ton of Captain America props (and a few Thor and Iron Man 2 doodads) off for a pretty penny.

Many of the marquee items are expected to go for thousands of dollars, but Marvel has managed to sneak in a few gewgaws for the price-savvy collector. Here's a rundown of some of the most thrilling keepsakes to buy if you're not interested in remortgaging your house.
